SKORPIOS (or Scorpius) was a giant scorpion sent forth by the earth-goddess Gaia to slay the giant Orion when he threatened to slay all the beasts of the earth. Orion and the Scorpion were afterwards placed amongst the stars as a pair of Constellations. The two opponents are never seen in the sky at the same time, for one constellation sets as the other rises. The scorpion's claws were originally formed by Libra (from Greek Mythology).
